Maxim Integrated MAX535ACUA

Description
The MAX535/MAX5351 are low-power, 13-bit voltage-output digital-to-analog converters (DACs) with precision output amplifiers in 8-pin packages. The MAX535 operates from a single 5V supply, while the MAX5351 operates from a single 3.3V supply. Both devices draw only 280μA of supply current. The output amplifier's inverting input is available to the user, allowing for specific gain configurations, remote sensing, and high output current capability. This makes the MAX535/MAX5351 ideal for a wide range of applications, including industrial process control. Other features include a software shutdown and power-on reset. The serial interface is compatible with either SPI/QSPI or Microwire. The DAC has a double-buffered input, organized as an input register followed by a DAC register. A 16-bit serial word loads data into the input register. The DAC register can be updated independently or simultaneously with the input register. All logic inputs are TTL/CMOS-logic compatible and buffered with Schmitt triggers to allow direct interfacing to optocouplers.
